Barbi Twins Shane and Sia, along with pals Daniel DiCriscio and Chyna Doll joined an animal rights protest in LA on Friday in support of stricter pet food laws. It was a wacky menagerie hoping to protect their precious pooches.

Dressed, as they explained, as dead black cats because it was Friday the 13th and they wanted to represent "the unlucky animals that died," Shane and Sia talked about the death of their beloved pet kitty who fell ill from poisoned pet food, and encouraged pet lovers to think more about what they feed their Fidos.
